.ZLKGCEFFICATION forming part of Letters Patent No. 323,658, datedAugust 4, 1885.

Application filed April 14, 1385.

To aZZ whom it may concern.-

Be itknown that I, J nULnos GAMBLLEE, of Crcsskill, in the county ofBergen and State of New Jersey, haveinvented a new and Improved Door, ofwhich the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding partsv in all the figures.

Figure 1 is a front elevation of a door-casing and door to which myimprovement has been applied. Fig. 2 is a sectional elevation of thesame taken through the line :0 m, Fig. 1. Fig. 3 is a front elevation ofthe central part of the operating mechanism. Fig. 4 is a sectional planview of the same taken through the line y 3 Fig. 3, and showing a partof'the door in section. Fig. 5is a sectional plan view of the same takenthrough the lines 2 2:, Fig. 3, and showing part of the door in section,and with part broken away. Fig. 6 is a sectional elevation of a part ofthe same taken through the linear to, Fig. 3. Fig. 7 is a sectionalelevation of a part of the same taken through the line o c, Fig. 3.

The object of this invention is to provide doors having top and bottomopenings with a mechanism constructed in such a manner that the saidopenings will be closed as the dooris shut and uncovered when the dooris opened, that the said mechanism can be so adjusted that the door canbe opened and closed without affecting the covers of the openings, andthat the openings can be uncovered and closed while the door is shut.

The invention consists in the combination, with a door having top andbottom openings, of slides for closing and uncovering the said openings,and a mechanism. for operating the said slides automatically and byhand, as will be hereinafter fully described,and then pointed out in theclaims.

(No model said slide can be drawn up into the said groove to bring itslower edge flush with the lower this construction, should the floor beinclined or an obstruction be left upon the floor A within the doorway,the rod F will yield and allow the slide E to take an inclined position.The rod F and slide E are held up by a spiral spring, G, placed upon thesaid rod, with its lower end resting against the shoulder at the lowerend of the groove, in which the said rod is placed, the said shoulderbeing faced with metal to prevent it from being worn. The upper end ofthe spring G rests against a shoulder or enlargement of the upper end ofthe said rod F. In the upper end of the rod F is formed a perforation toreceive a pin, H, attached to the forward side of the lower end of thebar I, which slides upon a plate, J, secured in a recess in the middlepart of the door O. The upper and lower parts of the sliding bar I areslotted to receive pins K L, attached to the upper and lower parts ofthe plate J, to keep the said sliding bar I in place as it moves up anddown.

To the forward side of theupper ends of the sliding bar I is attached apin, M, to enter a perforation in the lower end of the rod N, the upperend of which is provided with a screwthread, and is screwed into ascrew-hole in the plate 0, or in a lug or nut formed upon or rigidlyattached to the said plate 0, so that the said plate will be moved upand down by and with the sliding bar I. The plate 0 slides up and downin a recess in the center bar of the door-frame, and has a number ofperforations, P, formed through it for the passage of air.

In the upper parts of the panels of the door G door, and when thesliding plate 0 is raised the perforationsl will be opposite the spacesbetween the perforations Q, and the passage of air will be prevented.

To the upper part of the sliding bar I is secured the upper end of aspring, R, which is made with a lateral extension on its lower end,which overlaps the upper part of the bar S. The bar S rests and slideson the plate J, and is slotted to receive the pin T, attached to thesaid plate J to serve as a guide to the said bar S.

To the lower side of the extended lower end of the spring R is attacheda pin, U, to enter a hole in the upper part of the sliding barS, andcause the said bar S to move up and down with the spring R and bar I.

To the lower end ofthe sliding bar S is pivoted the end of the long armof the elbowlever V, which is pivoted at its angle to the plate J Theshort arm of the elbow-lever V projects upward, and has a slot, WV,formed in it to receive the flattened neck in the inner end of the rodX.

In the side of the short arm of the elbowlever V is formed an openingleading into the slot W, so that by sliding the end of the rod X downinto the lower end of the slot W the said rod can be disconnected fromthe said lever. The rod X slides in a hole leading in from the outeredge of the door 0, and its outer part is enlarged and hasits outer endbeveled, as shown in Fig. 5, so that the said rod can be pushed inwardby havingits outer end come in contact with aplate, Y, attached to thedoor-jamb.

The outer part of the perforation in which the rod X Works iscountersunk to receive the enlarged outer part of the said rod X, and toreceive the spiral spring Z, placed upon the rod X, with its outer endresting against the shoulder of the said rod, and its inner end restingagainst the shoulder at the inner end of, the countersink of theperforation in which the said rod works, so that the said spring Z, willhold the rod X, pressed outward in position to strike against the plateY,and the long arm of the elbow lever V, the sliding bars S I, the rodsF N, and the slides E 0 will be raised against the tension of the springG, uncovering the openings at the bottom and top of the door, andallowing the said door to swing open and shut freely.

When the door is shut, the outer end of the rod X strikes against theplate Y, and the said rod is pushed inward, which lowers the long arm ofthe elbow-lever V and the sliding bars S I, the rods F N; and the slidesE 0, closing the bottom and top openings of the door 0. The guide-pin Kprojects to receive and serve as a pivot to the hub of the double cam a,which is made in crescent shape, and has the convex edge of its upperarm beveled upon the outer side to engage with the recessed edge of thespring R, beveled upon the inner side, so that when the said upper armof the double cam a is turned against the edge of the said spring, thelower end of the said spring will be raised, withdrawing the pin U fromthe sliding bar S, so that the door can be shut without covering thebottom and top openings of the said 'door. \Vhen the double cam a isturned in the other direction,its lower arm engages with the flange,rib, or shoulder 1;, formed upon the sliding bar I, and forces the saidbar, the rods F N, and the slides E O downward, covering the bottom andtop openings of the door. By this construction the slides E O can beadjusted independent of the rod X. cis a key, knob, or other handle,placed upon the hub of the double cam a, and secured in place by a pin,d, passing through the said hub and the shank of the said key, or othersuitable means.

Having thus described my invention, I claim as new and desire to secureby LettersPatent l. The combination, with a door,O, having top andbottom openings, of the slides O-E-I, the rodsN F, connectingthe saidslides, the spiral spring G, placed upon the lower rod,F, the springR,attached to the slide I, and having pinU, the sliding bar S, havingperforation to receive the said pin :U, the elbow-lever V, having itslong arm connected with the slide S, and having a slot,W, with sideopening in its short arm, the rod X, engaging'with the slotted arm oftheelbow-lever V, and the spiral spring Z, placed upon the said rod X andpressing it outward,substantially as herein shown and described, wherebythe said slides will be operated automatically to cover and uncover thetop and bottom openings as the door is closed and opened, as set forth.

2. The combination, with the door 0, the central slide, I, connected bythe rods N]? with the top and bottom slides,O-E, and havingshoulder b,and the spring -R attached to the said slide I, and having its recessedlower end beveled, of the double earn a, having-its upper arm beveled,and the key a, secured to the cam-hub, substantially as herein shown anddescribed, whereby the said slides can be throwrtont of connection withthe rod X, and the said top and'bottom slides operated by hand, as set'forth.
